Demonstrators tried to surround a mock shack erected in protest as authorities moved in to destroy the structure.

The 'Rhodes Must Fall Movement' says the shack highlighted the alleged lack of accommodation for black students.

Two vehicles, as well as an administration office, were petrol bombed.

Ally says while the movement fights for important student issues, members are discrediting themselves by resorting to violence.

"I think it's regrettable because it does not [give] the movement any credit. I think that biggest tragedy is that it then distracts attention away from the very legitimate issues that Rhodes Must Fall brought to the attention of not just the university, but nationally."
